Did you check Adobe's website with your account? If you registered CS6, Go to my Adobe, and there is a link to your products. Your S/N will be listed there.
This would help you in confirming your Serial. If it still does not solve your issue then contact Activation Support:
Click the Chat Now button at the end of the page and talk with a live agent who would resolve it ASAP.
ok, it shows that I have CS6 and LR4 .. but .. "S/N" is ... where should I see it?
Thanks for such an incredibly fast reply!
OMAN! You are a life saver ... That did it!
THANK YOU Ashutosh.Nigam!!!!!!!!!!!
